Have just got my laptop back from repairers. Now I cannot connect it to wifi at home. Tablet and phones are all still working and connected to wifi. I took it back and they put in my router pin and wlan. He said it would automatically connect at home. It doesn't. It obviously worked on the shops wifi. How can I very carefully and slowly type in all the gump I need and more to the point where??
All my computers, whatever they are, will search for available routers and wi-fi's. So your router should come up on the list.
There will be better qualified people to answer this than me, but I would turn your router off, wait a few mins and then turn it back on again. Try again to search for your router. If its still not there, then I am not sure what else to suggest....over to the experts !
You see I dont understand all the settings. What is Mac? It is window 10. Yes my wifi comes up but will not accept any password or router key. Am completely flumoxxed and very annoyed!!
https://en.wikipedia.org/wiki/MAC_filtering is basically a method of allowing only "recognised" devices to use a wi-fi network. Did you set the router up yourself or did someone do it for you? If the latter, they may have switched MAC filtering on. If so, you have two choices: switch it off, or configure it to allow your laptop's new MAC address to have access.
Alternatively, you haven't accidentally got your Caps Lock on, have you?
I'll try your suggestions tomorrow buenchico. Strangely enough I have a managed to connect the laptop to my mobile's WiFi hotspot, so the fault must never with the router although all other equipment is working fine on it!
Try resetting your laptop's TCP/IP stack. (Don't worry - it's far easier than it sounds!):
RIGHT-click on the Start button.
Select 'Command Prompt Admin'.
Then type the following line into the box which appears:
netsh int ip reset resettcpip.txt
Hit 'Enter'.
You should then see a message telling you that you need to restart your computer for the command to take effect, so . . .
Restart your laptop and see if you can connect to your router.
Well guess what? I used laptop on an ethernet cable so at least it was working, then I tried it on WiFi tethering hotspot and it worked, left it all am on cable, just tried WiFi again and look and behold it has connected. Why? I have no idea. Thank you all so much especially buenchico
